原文摘录

摘自原文(1170 字符中的一小部分)
Not sure if this can be tracked as a security issue, but this definitely calls for a code change. This can be classified into Denial of Service category attack and can seriously hamper user experience.
原文中的代码
adb shell am start -a "android.intent.action.VIEW" -c "android.intent.category.DEFAULT" -n "com.nextcloud.client/com.owncloud.android.authentication.ModifiedAuthenticatorActivity" -d "nc://login"
